Sorry you're having issues with your game! However, did you follow the steps here? You mentioned your installed the patch 1.63, however did the launcher do this for you on its own or did you use the MANUAL patch which is located in the link provided?

Please follow the steps 2 through 5 within the topic I sent you and then your game should work!

If you have any more issues or anymore questions, let us know. Good luck!

If you want to install worlds, you still have to use the launcher or at least try it. Copy the ".sims3pack" to My Documents/Electronic Arts/The Sims 3/Downloads. Now start up the launcher (keep in mind that it will take a while). Go to the "installed items" tab and mark the world. Click on the "Install"-button at the bottom.
